java后台调取第三方put请求并传token

在Java后端调取第三方API时，如果你需要通过`PUT`请求并且附带`token`，通常会涉及到以下几个步骤：

1. **创建HttpClient实例**：
首先，你可以使用`java.net.HttpURLConnection`或者更现代的`org.apache.http.client`库来创建一个HTTP客户端。

import org.apache.http.HttpHost;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPut;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

CloseableHttpClient httpClient = HttpClients.createDefault();
HttpHost targetHost = new HttpHost("第三方API地址", 80, "http");

2. **添加Authorization头部**：
使用`BasicHttpAuth`模块添加包含`token`的`Authorization`头。例如，如果`token`是Base64编码的，可以这样做：

String encodedToken = Base64.getEncoder().encodeToString(("Bearer " + yourToken).getBytes());
CloseableHttpResponse response = null;
try {
    HttpPut putMethod = new HttpPut(targetHost.toURI() + "/your-endpoint");
    putMethod.setHeader("Authorization", "Basic " + encodedToken);
    // ...其他请求头设置...
    putMethod.setEntity(new StringEntity(yourRequestBody));
    response = httpClient.execute(putMethod);
} catch (Exception e) {
    // 处理异常
}

3. **处理响应**：
获取并关闭响应，解析返回的数据。记得在完成操作后关闭连接：

try {
    int responseCode = response.getStatusLine().getStatusCode();
    if (responseCode == HttpStatus.SC_OK) {
        String responseBody = EntityUtils.toString(response.getEntity(), StandardCharsets.UTF_8);
        // 处理响应内容
    } else {
        // 处理错误状态码
    }
} finally {
    response.close();
    httpClient.close();
}
